BURNER FOR ACETYLENE GAS.

SPECIFICATION forming part Of Letters Patent N 0. 731,907, dated June 2 1903- Applieation filed September 30,1902. Serial No. 125,385. (No model.)

, To all whom it may concern.-

Be it known that We, PAUL JACOB and CURT JACOB, subjects of the King of Saxony, residing at Zwickau, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Burners for i I Acetylene. Gas, of which the following is a specification.

. This invention relates to gasburners; and the object of the invention is to provide a simple device of this character having efiective means for regulating the quantity of air to be mixed with the gas in the burner-tube, and although the improved burner is capable of advantageous use. in connection with different kinds of gas it has been found satisfactory as a burner for acetylene gas.

The invention is clearly illustrated in the accompanying drawings, forming 'a part of this specification, and in which Figure 1 is a sectional elevation of a burner including our invention and showing the manner of using the same. Fig. 2 is an elevation of theburner-tube and air-regulator carried thereby. Fig. 3 is a detail in eleva tion of a difierent form of regulator.

Like characters referto like parts in the several figures. V

Referring to Fig. 1, the numeral 1 indicates a burner-tube, it having threadedinto its lower end the gas-nipple 2 and being provided substantially in the same plane as the upper end of the nipple with a series of airx1 inlets of the usual kind. In said Fig. l and also'in Fig. 2 the air-regulator is shown as consisting of a sleeve 3, in threaded engagement at dwith said burner-tube. From this it will be evident that the air-regulating sleeve is vertically adjustable, whereby it maybe raised or lowered across the said airinletsin orderjto, increase or decrease the effective area thereof and correspondingly con trol the amount of air flowing into the burnertube 1. The lower end of the air-regulating sleeve is shown as bell-shaped in order to I collect atmospheric air and properly direct the same through saiddair-inlets. The burnertube 1 contains the superposed mixing-chambers 8 and 9 for the gas and air, respectively, the upper chamber being formed in the tube 10, fitted upon the upper side of tube 1. This tube 10 is connected with the usual yoke 11 or its equivalent in some familiar manner, and it is covered by a cap 12, having a gas-outlet 13, under which one .or more disks of gauze 14, as is customary in this class of devices, may be situated. As the bell-shaped extensiomupon the body of the vertically-adjustable flair regulating tube covers the air-inlets alluded to, it is necessary to provide some means for effecting the accurate adjustment of the body of the sleeve. with respect to said inlets, and this is eifectually accomplished in the following way, although the invention is not limited to the means nowto be described: Upon the burnertube 1, near the lower end thereof, is a strip 7, constituting a stop and which has a vertically-elongated slot to receive a set-screw 7c tapped into said burner-tube, it being understood that the slot and setfscrew provide for vertical adjustment of the strip. The upper end of said strip or stop is adapted to intersect the line of the air-inlets, and said strip preferably intersects one of said air-inlets in order that its accurate adjustment can be secured. After the regulating-sleeve has been raised the strip may be adjusted so as to overlap more or less one of said inlets. When the strip or stop is adjusted to the proper extent, the air-regulating sleeve will be lowered until its body strikes the upper end of the stop. It will be understood, therefore, that even though the bell-shaped extension at the lower end of the air-regulating sleeve covers the air-inlets said sleeve may be accurately adjusted through the agency of the adjustable stop. 7

Instead of connecting the air-regulating sleeve to the burner-body by a screw-threaded joint it may be united thereto in other ways. In Fig. 3 the gas-regulating sleeve 5 has in its upper portion a plurality of elongated slits,wl1ich form yieldable fingers which engage the burner-body above the air-inlets therein. A gas-regulating sleeve constructed in this manner can be readily raised and low ered upon the burner-body.

Having thus described our invention, what 100 we claim is- 1. The combination of a burner-body having one or more air-inlets, a vertically-adjustand constituting a continuation of th able air-regulating sleeve upon the burnerbody, provided with a bell-shaped lower end, and a vertically-adjustable stop upon the burner-body arranged to be engaged by the body of said sleeve.

'2. The combination of a burner-body having one or more air-inlets, a vertically-adj ustable air-regulating sleeve upon the burnerbody, provided with a bell-shaped lower end, and a vertically adjustable stop upon the burner-body arranged to be engaged by the body of said sleeve and adapted to intersect one of said inlets.

3. The combination of a burner-body having a line of air-inlets, a regulating-sleeve adjustable vertically on the burner-body and having a bell-shaped lower end, and a vertically-adjustable stop, the upper end of which is adapted to be engaged by the body of the PAUL JACOB. OURT JACOB.
